如何将 Eequitable 扩展到已经扩展和混合的类?

Question

如何扩展和实现 Eequitable 到类 CategoryListPage ？ https://pub.dev/packages/equatable

这是我的类声明代码：

class CategoryListPage extends StatefulWidget with NavigationStates {
List<LanguageObject> _languagelistcategorydata;
String _titleappbar;
CategoryListPage(List<LanguageObject> languagelistcategorydata, String titleappbar) {
_languagelistcategorydata = languagelistcategorydata;
_titleappbar = titleappbar;
}
@override
_CategoryListPageState createState() => _CategoryListPageState(_languagelistcategorydata, _titleappbar);
}

Answer 1

class CategoryListPage extends StatefulWidget with NavigationStates, Equatable {
List<LanguageObject> _languagelistcategorydata;
String _titleappbar;
CategoryListPage(List<LanguageObject> languagelistcategorydata, String titleappbar) {
_languagelistcategorydata = languagelistcategorydata;
_titleappbar = titleappbar;
}
@override
_CategoryListPageState createState() => _CategoryListPageState(_languagelistcategorydata, _titleappbar);
}

这将起作用。如果您想了解有关with关键字的更多信息，请参阅此处
